Ho do I calculate date plus days without weekends in Table Transformer SQL

I'm looking to have a table with one column of dates, another column of days and the 3rd column calculated by adding the two and excluding the weekends.   Say if date Jan 1 falls on a Monday and i need to add 8 days, the resulting 3rd column will be Jan 10 (Wed the following week).  I followed the following article but it is a straight days add.

Thanks in advance for your help

Hi @Fulbert Lato ,

You may try the following SQL query:

Tue 2-1.pngSELECT *,
T1.'Period' +
2 * FLOOR(T1.'Period' / 5) +
WHEN 'Start Date'::Date->getDay() = 0 THEN 1
WHEN 'Start Date'::Date->getDay() = 6 THEN 2
WHEN ('Start Date'::Date->getDay()) + T1.'Period' % 5 > 5 THEN 2
T1.'Start Date'))
AS 'End Date'

Tue 2-2.pngThe query counts the number of Saturdays and Sundays for your period plus checks if the Start Date belongs to the weekend and "extends" the period (i.e. moves the End Date further) for the calculated number of holidays.

That is brilliant!  Thank you!
